I am finally back in the pool, training for the Ralph's half in March. I seem to really have trouble with the lower part of my body dragging/sinking while freestyle swimming. Does anyone have any tips to correct this. I am trying to push my head down. Any advice would be great!!!

ditto the other comments and also your forward arm position can affect your leg position. The TI video illustrates this pretty well. Some people have better ballance with their arm in the 4:30 or 5:00 position than in the staight 3:00 position, so as your arm sits lower in the water it helps pull your lower body higher.

pressing your buoy and looking down instead of out in front of you really works. It took me a while to get it, but once you do you will feel the diffrence. Do you have the Total Imersion Swimming book???

I'll echo what the others have said. Keep head and chest down, but be particularly conscious of getting the chest down in the water. It doesn't necessarily follow the head. I found it made a big difference.

I have the same problem. I bought the Total Immersion book, and I can't get past the first drill (floating on my back) because my bottom half sinks. I'll keep trying at it until I get it right, and will gladly share what I learn.

Keep practicng, the TI video helped tremendusly and I finally did what felt like a total exaggeration, swimming downhill, as TI says, and lo & behold, up comes the legs, what a wonderful feeling it is when it finally comes together - I nearly doubled my previous distance yesterday - I am doing the Memphis in May Oly distance and I finally feel I will do the swim very comfortably, maybe not fast but also not having my HR thru the roof & emerge screaming "Oxygen, Oxygen, give me Oxygen"
